The project, constructed by Sunpower Corp, is expected to generate 579 megawatts of power when completed by the year-end, making it the largest solar project in the world, Citigroup said in an emailed statement.

Solar Star is expected to provide enough energy to power more than a quarter million homes, the company said.

Citigroup also raised $862 million for Panama’s first metro, which transports 30,000 commuters per hour.

In 2012, Bank of America Corp set a goal of $50 billion to provide loans and other financing for environmentally friendly energy projects over 10 years.

The same year, Goldman Sachs Group Inc set a 10-year target of $40 billion for investments in renewable energy projects.
